RDP (Redispersible Polymer Powder/Redispersible Powder) or VAE is a water-soluble re-dispersible powder. It is a copolymer of ethylene and vinyl acetate. It d issolves in water easily and forms emulsion quickly , RDP could offer s trong adhesive and stretching force to i mprove the workability, flexibility and water-proofing of the materials
.Redispersible Polymer Powder is a kind of free-flowing white powder,which is spray-dryed by polymer emulsion and after subsequent treatment to keep the stability of powder appearance and character. The mainly application is in construction dry-mixed mortar,and have excellent performance in increasing the dry mortar cohesion,adhesion and flexibility.
